The Shambaa people, also called the Sambaa, Shambala, Sambala or Sambara, are a Bantu ethnic group. Their ancestral home is on the Usambara Mountains of Lushoto District, Korogwe District and Bumbuli District. They are native to the valleys and eastern Usambara Mountains of Korogwe District, Korogwe Urban District and western Muheza District of northern Tanga Region of Tanzania. The word Shamba means "farm", and these people live in one of the most fertile Tanzanian region. Shambaai in Kisambaa means "where the banana's thrive". In 2001, the Shambaa population was estimated to number 664,000.

The Usambara Mountains of northeastern Tanzania in tropical East Africa, comprise the easternmost ranges of the Eastern Arc Mountains. The ranges of approximately 90 kilometres (56 mi) long and about half that wide, are situated in the Lushoto District of the Tanga Region. They were formed nearly two million years ago by faulting and uplifting, and are composed of Precambrian metamorphic rocks. They are split into two sub-ranges; the West Usambaras being higher than the East Usambaras, which are nearer the coast and receive more rainfall.
